摘　　要：以马铃薯品种‘费乌瑞它’、‘大西洋’和‘克新13号’为试验材料,于盛花期进行叶面喷施2-N,N-二乙氨基乙基己酸酯(Diethyl aminoethyl hexanoate),简称DTA-6;烯效唑(Uniconazole),简称S3307;氯化胆碱(Choline chloride),简称Cc。通过比较块茎重量和块茎内可溶性蛋白含量、维生素C含量、淀粉含量、还原糖含量以及酚类物质含量,分析3种植物生长调节剂对马铃薯产量和品质的调控效应。结果表明,DTA-6可显著提高‘大西洋’和‘克新13号’大薯重量,Cc可显著提高‘大西洋’大薯重量;各处理对可溶性蛋白含量没有显著性影响,但都显著提高了‘费乌瑞它’酚类物质的含量;DTA-6可显著提高‘费乌瑞它’和‘克新13号’维生素C的含量,而Cc可显著提高‘费乌瑞它’淀粉含量,DTA-6和Cc处理可显著提高‘克新13号’还原糖含量。A field experiment was conducted with three potato cultivars,‘＇Favorita’,‘Atlantic’ and ‘Kexin 13’ in this study. Three regulators, ＇Diethyl aminoethyl hexanoate （DTA-6）＇, ＇Uniconazole （S3307）＇ and ＇Choline chloride （Cc）＇ were used by foliar application, The aim of this experiment was to study the effects of plant growth regulators （PGRs） on yield and nutritional qualities of potatoes by comparing the change of tuber weight and the content of soluble protein, vitamin C, starch, reduced sugar and hydroxybenzene. DTA-6 increased the weight of large-sized tubers of＇Atlantic＇ and ＇Kexin 13＇, and Cc had the same effect on ＇Atlantic＇. There was no significant impact on soluble protein content with those three treatments, but they significantly increased the content of hydroxybenzene of ＇Favorita＇. DTA-6 significantly increased the content of vitamin C of ＇Favorita＇ and ＇Kexin 13＇, and Cc increased the starch content of＇Favorita＇, significantly. DTA-6 and Cc significantly increased the content of the reducing sugar content of＇Kexin 1 3＇.
